About Flamsteed Astronomy Society
The Society was founded in 1999, and is part of the membership organisation of Royal Museums Greenwich.
The Flamsteed has around 500 members who represent the full range of interests and experience in astronomy. Many are beginners. We are named after the first Astronomer Royal, John Flamsteed.
Our lecture meetings are held once a month between September/October and May/June, usually on a Monday evening, in the lecture theatre of the National Maritime Museum, or in the Peter Harrison Planetarium at the Royal Observatory Greenwich (ROG). The Society regularly holds observing evenings using members’ own telescopes. In addition the Society stages viewing sessions with the ROG’s Great Equatorial Telescope, the largest of its kind in the UK, and seventh largest in the world.
